How do we prepare for environmental measurements after "Europe 1993"?
Scientific measurements, and chemical measurements in particular, play an important part in modern society and are being used increasingly as a basis for important decisions and regulations in legal, medical and environmental fields. This responsibility, however, means that the reliability of such measurements is of the utmost importance. A growing awareness, of both public and of governments, of environmental issues means that environmental measurements are becoming a particular case in point. Here, measurements must be comparable across borders, while for chemists the prime concern is the loss of credibility that a lack of reliability might generate. In order to achieve both credibility and comparability, the fulfilment of the following requirements seems necessary: i) the expression of all results of environmental measurements in the SI unit, the mole, for amount of substance; ii) ensuring their traceability to the mole; iii) the assessment of their real performance through regular participation in external (border-crossing) quality assessment programmes using undisclosed, real-life samples. In this paper, examples of highly unsatisfactory measurement performances, together with possible improvements, are discussed and the need for an ethical approach by environmental scientists is highlighted.
